NATHAN THOMPSON, OF BROOKLYN, NEW YORK.

Specification forming part of Letters Patent No. 133,271, dated November19, 1872; antedated November 18, 1872.

To all whom it may concern:

Be it known that I, NATHAN THOMPSON, of the city of Brooklyn, in Kingscounty and State of New York, have invented an Improvement inCartridge-Extractors, applicable to Breech-Loading Ordnance, of whichthe following is a specification:

This invention is designed to facilitate the extraction of thecartridge-shell from breechloading ordnance after the breech-block hasbeen removed from its position for firing and consists in a novelarrangement of a springborne lever to be operated by a spring bornepercussion-rod.

Referring to the drawing, Figure 1 represents a horizontal section ofthe breech portion of a gun with my invention applied; and Fig. 2 is arear view of the same, the breechblock in each figure being removed.

The same letters indicate like parts in both figures, and. in which- Arepresents the body of the gun; B, its bore or barrel; 0, thespringborne lever; and

D, the percussion rod, by which the lever G is operated and caused toextract the cartridge by its underlapping of the flanged end of thelatter. E is the breech-block holder, constructed in a similar manner tothat described in my applications for Letters Patent, which were allowedMarch 28, and April 12, 1872, respectively, and therefore need nofurther descrip tion here.

The operation of this extractor will be apparent from the drawing, thebreech-block being rolled aside to clear the flange of thecartridge-case, in which position it is retained by the screw G, and thespring-rod D, being sudnance, the cartridge extractor herein described,consisting of the combination of the spring-borne lever O andpercussion-rod D,

when arranged for operation substantially as set forth.
